To 4all whom it may concern:

Be it known that I, J osier NEMErz, .a subiectof the Emperor of Austria, residing at Vienna, Austria-Hun gary, have invented certain new and useful Improvements in Fire-Arms and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such aswill enable othersk skilled in the ar'tto -which it appertains to make and use the same, reference being had tothe accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

. My invention relates-to a novel construction ofmagazine {ire-arms in which the magazine is moved at right angles to the axis of the bar' rel and the tiring-pin and the invention conslsts, first, in a magazine tirearm,.the combination, with the barrel, a laterally-movable cartridge-magazine, a ham mer provided with a iiring-pin, a guide-rodfor the same, and a hammerrod hinged to said tiring-pin, of a sliding triggerguard and means, substantially'as hereinafter set forth, whereby a lateral movement is im-` parted to the magazine, and the firing-pin, through the medium-,of its hammer-rod. is' locked into position for iringb'y the operation of; the ytrigger-guard, substantially as hereinafter described, 'and for the purpose specified; second, '1n a magazine tire-arm, the combination, with the barrel, a laterally-movable' car-l tridge-magazine, a hammer provided with a firing-pin, a'gui'de-rod for4 the same, a hammerrod hin ged to said ring-pin, a sliding triggerguard', and means, substantially as hereinafterl set forth, whereby a lateral movemen is imparted tothe magazine, and the tiring-pin', through the medium of its hammer-rod, is lockedA Into position for tiring, of the trigger v and the actuating-spring,substantially as' here' inafter described and shown; third, in arbreechloading magazine-gun, the combination, with tliering-pima magazine arranged tobe moved at right .angles to the axis of said firing-pin, of a trigger-guard adapted to retract the pin,lock4 ,it intoI position for iirin g, and simultaneously .movethe magazine to bringa fresh cartridge f in position for firing, substantially as hereinafter more fully described; fourth,the invention further consists iu struction of parts and their combination with each other, as hereinafter fully described, and shown in the accompanying drawings, in wbich- Figure 1 is a longitudinal section of so much of a gun as is necessary to illustrate my invention, the parts being shown in the position after ring. Fig. 2 is a like view showing the parts in position ready for firing. Fig. 3 is a transverse section on line :c a: of Fig. 1. Fig. 4 is a longitudinal section of the open magazine. Fig. 5 is a rear elevation of the same and its casing. Fig. 6 is an under side view of the magazine, its casing, and the guide-rod for the hammer. Fig. 7 is a top view of the magazine, its casing, and the guide-rod for the hammer. Figs. 8, 9, 10, 11, and 12 are detail views.,

Like letters' of reference are employed to indicate like parts wherever such may occur in the above tgures of drawings.

The 'magazine is constructed oftwo parts, a. a', hinged together, as shown. Itmay beprovided with six or more chambers to receive au equal number of cartridges. Itis so arranged in the gun as to be moved laterally every time the hammer is retracted into position for liring-rthat is to say, whenever the hammer is brought to full-cock. The extent of this lateral movemcntis'such as to bring a fresh cartridge in line with the bore ofthe barrel when- .ever the hammer is retracted. The two parts aa ot' the magazine are provided with semicircular recesses or grooves, so that when the two parts are locked together chambers are formed that have the form of and securely inclose a cartridge each.

At the rear end of the lower portion, a, of

certain details of conthe magazine ishinged a locking-plate, a2, that v extends over the cartridge-chambers, and has a-nurnberV of perforations'equal to the number of said chambers for the passage of the tiringpin.

, The connectionof the locking-plate a2 with the part a ot' the magazine is'such that said plate will have but a limitedbackward movement when the part a' is raisedthat is to say, the backward movementof a2 is such that it.l

e l remesa 'will always be in proper position forengagement with the locking-plate a3 on the part a' of the magazine. Theplatea3 extends across the rear face ot' the locking-plate a2 when the magazine is closed, as shown, Figs. 1, 2

respondingly-shaped guide-groove of the ma gazine-casing, hereinafter more fully described. By means of this projection and the iange or projection b' of the magazine-casing the magazine is held yagainst. forward or backward mol tion, while it-is adapted to be moved laterally in the dovetailed groove of the casing.

The casin g bis composed of a framethat has a screw-threaded tubular head for the reception ofthe barrel e. The rear end, b2, of the frame A forms the breech-block, the inner face'of whi ch has the form oia segment of a circle whose center is that of the pivot-pn of the magazine-lid a', as shown, Figs.'1,2, and 4,' and against Kwhich bears the'curvedlockng-platea.3 of said lid. The outer face of the locking-plate a2 and both the outer and inner faces ot' the plate a3 also form segments of circles drawn from the above described center, and said faces are ground true, so as to t accurately one against the other. l

The breech-block b2 ot' the magazine-casing carries a small safety-pin, t', which is pressed into a recess, al, formedin the locking-plate a3 of the magazine by .a spring, i', and serves to -lock the locking-plates a? a3 against accidental displacement.

the nose cl3 comes in contact with the arm 2' When the hammer is retracted of the pin -t' and disengages it from the recess alito permit the opening of the magazine.

The opposite sides b3 of the frame or casing b are connectedtogether centrally by acrosspiece, b, in which is formed the dovetailed groove b5, above mentioned. In the bottom of 4this 'groove b5 is formed a slotb", Fgs.'4 and -7, rectangular or prismatic in cross section, in

` which ride the guide-pins a5, formed on or at# tached to theldov'etailed proiec'tion a* of the magazine.

' some .distance forward here of the barrels,

Throughthe medium of a beveledl plate, c, that is connected with the hammer guide-rod, and that is brought in contact with thepinsa" when the hammer is retracted to fullcock,-the magazine is moved laterally a distance suficient to bring a fresh cartridge in line with the as hereinafter referred to.

c is the hammer. Shown in front elevation, Fig. 9.) It is provi ed on opposite sides-with guide-cheeks that are extended to project of the hammer, and at their forward end are hinged lto the hammerrod c. These cheeks c? serve to holdthe hammer. in proper position upon its guiderod c,

. upon which itis adapted to slide backend forth.

, Thehammer-rod c5 has a projection or nose, c, adapted to engage a stop, g3, on the covering plate or strap g, said hammer-rod being held `depressed by a spring, c7, for purposes presently explained.

l In order to properly guide the hammer-that is to-say, in order to insure the correctforward movement of the firing-pin, so that it will always strike the cartridge centrally-the cheeks c3 may be provided with a tongue or pin, and -the rod c2 with a groove, as shown in Fig. 9; or said cheeks may be made toinclose the guiderod, in which latter case no other guiding devvices will be necessary.

Upon the .guide-rod c2 is rigidly attached a safetyplate, c, Figs. 1, 2, and 8, that is pro vided with a central aperture for the passage of the firing-pin. A

0u each side ofthe central aperture the plate c8 carries a pin, c, the distance between the pins enter into the openings provided for. the

passage ot' the firing-pin the magazine will always bein the required position for said piu to come in contact with a cartridge to be fired.

The length of the pin-s 09 is equal to the IOO thickness of the breech-block b2 and the locking-plate a3 ot' the magazine, and in form said pins are like the ringpi'n with its strikingvpoint removed.

' The apertures in theloching-plate a? of the magazine are of the same diameter as the point of the tiring-pin, hence smaller than the openings in the parts a3 b2, as shown, Figs. l 'and-l2, so that under no circumstances can the pins o9 be brought in contact 'with the eartridge.

The hammer guide-rod has its bearings intwo supports, g g2, formed on the covering or lock-plate -or strap' g. Its forward end, iu rear of the support g', is angular in crosssection, Which,together with 4the springv c1", serves to maintain it iujproper position.

A Spring, c, ou the guide rod c2 bears against 'the hanimerat one end, and at the other against the support g2, and holds the said hammer in co tact with the safety-plate c when the ham er has been thrown forward. v It'will be seen that the hammer moves with the rod c2 in one direction and independently of said rod in av reverse direction.

When the parts are in the position shown'in Fig. 1 -that is to-s'ay', after firingand the rod IIO be compressed. This rearward inovementepf' eis-1,6m

t the hammer through the plate continues as long .are-placed in the magazine so that the edges as the trigger-guard is pulled back, or as far as -the rod can move backward. When, how y ever,1'.he full-cock stop on the hammer-rod engages that onthe covering plate or'strap g to arrest the forward movement of the hammer under the tension of the spring all, then the trigger-guard is released, and the rod is free to move forward under the tension of the spring 0.1 to bring the safety-plate c into the position above described before tiring, or before releasing the hammer by pulling the trigger.

The trigger-guard plate h is connected with the hammer guide-rod by means I of a pin, c, thatengages-'a recess in a block, c", attached to or formed on said plate. This block c* extends from the guard-plate' It through a slot, g5, in' the covering plate or strap g to the under side of said hammer guide-rod. The strap gis provided with a second slot,.g6, in rear4 of the trigger-guard, in which slides the guide. block'h, attached to the guard-plate h.

' When thegun is to beloaded the triggerguard plate h is pulled back by means ot' the handle on the trigger-guard h until the small- .pn'h Aonfthe' spring. h3 engages the recessl g4 1n the strap gto hold the guard-plate and guiderod against-forward movement under the tension ot' the springs cl 01,1, which are compressed bythe retraction of the guard-strap. When 'the parts are in this position themag'aziue can q be openedand loaded. *The charge consists of six ormore cartridges held at their rear endsA in a carrier, 7c, of card-board, thin wood, tin, orother. like material; as shown in Fi g. 12, and

of the carrier will lie in the recessesk formed `1n .the .locking-plates az a3 of said magazine. The magazine may now be locked, as described above, and the triggerl pnlledfback suiciently to cause its nose l' to engage the free end of the spring haud disengage its pin from the recess g4 in the strap g and cause the spring c1 to carry the hammer guide-rod forward until the stop or nose c6 on the hammer-rod is arrested by the-projectionor stop ga'on the strap g. This forward movement of the hamincr guide-rod also lproduces a like movement 1n the safety-plate c, which ,is now in contact with the breech-block, with its pins in the latter, andthe locking-plate a3 of the magazine,

Y as shown in dotted lines, Fig.l 2, and described -above. In this position the parts areat fullcock, land by pullingthe trigger the-pivote@- hammer-rod is disengaged from the `stop g3,

the'hammer is thrown 'forward b y theV spring c, and its tiring-pin c brought in contact with the cartridge. lAfter the tirin g of the lir'st cartrid ge two movements only are required to load and iire'the gunnamely, the retraction ofthe trigger-'guard and its plate until the4 nose or stop c6 is in engagement-with the stop g3., and the pulling of the ,triggerl to release the hammer. At every retraction of the trigger-guard, hammerrod,and hammer guide-rod the magazine is moved laterallya distance equal to that and bringa between two cartridges. This is effected by means of the beveled actuating-plate c on the guide-rod c2, the inclined edgeof said plate `beng`brought in contact. with one of the pins a5-of the magazine to move the latter laterally fresh cartridge in position for firing.

It'will of course be understood that it is not absolutely necessary that the cartridges should be held by a carrier. These may be .placed one by one,iu the magazine, if desired, 4and the recesses-kf may then be dispensed with; butwhen it is desired to Aload rapidly, then the advantage of the carrier becomes obvious.

A small sprng,b", attached to the magazine- `casing carries at its outer end ajstud or pin, 'that engages a recess, asf-in the under side of the magazine every time the latter is moved, .as described, to insure the proper position of the cartridge relatively to the barrel. The

power of the spring is such as tobe readily overcome' by that exerted by the'incliued plate c upon the pins a5 to move the magazine laterally.

In order -to provide a gas-tight connection between the barrelandmagazine, I employ a springwasher, w, and a plain washer, fw', inserted in a small recess formed in the rear end, c', ot' the barrelV e. VBy preference I form the spring-washer of steel and the plain washer of gun-metal. p

When all the -cartridges have been red o .-the magazine is reloaded, asabove described, and pushed from right to left until the iirst cartridgeon the right of the magazine is opposite the bore of the barrel.

If it is desired touse the gun as a breechloader, this may be done either' after all the cartridges have been fired off or by pushing the magazine toward the4 right until the extreme left chamber is opposite the bore of the barrel,'as in this po'stion of the magazine no further lateral movement can take place, as willbe readily understood.
